Abstract : CURV III, the latest of NUC's CURV vehicles, was used to survey radioactive-waste disposal sites near the Farallon Islands. Radioactive wastes encased in concrete-filled steel drums or concrete vaults were dropped at these sites from 1946 to 1965 in depths ranging from 2400 to 6450 feet. The objective of the survey was to determine the effectiveness of this disposal method and its short-term (10 to 30 years) environmental impact. To this end CURV III was employed to take 35-mm color photographs, make video tape recordings, and take benthic core samples and other specimens. This task was relatively simple because the vehicle's control system and hydraulic power package are readily accessible. Information gained during survey of these sites has added greatly to the limited knowledge of deep-ocean radioactive-waste disposal sites. (Author)
